PLOW.

SPECIFICATION forming part of Letters Patent No. 387,385, dated August7, 1888.

Application filed November 12, 1887. Serial No. 254,977. (No modeLl ToaZZ whom it may concern:

Be it known that I, GEORGE WASHINGTON \VHATLEY, a citizen of the UnitedStates, residing in the county of Dallas and State of Texas, haveinvented certain new and useful Improvementslin Flows; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it ap-1o pertains to make and use the same.

The object of my invention is to provide an improved plow stock or framehaving an adjustablefootto regulate the inclination or pitch of theplow-point. It is also my object to provide an adjustable clevis-supportadapted to be applied to a plow-beam.

In the drawings, Figure 1. is a side elevation of the plow stock orframe. Fig. 2 is a perspective view, enlarged, of the clevis-support.

A denotes the beam of a plow; B, the standard; C, a bracerodscrew-threaded to receive the nuts 0 e.

D denotes the foot, provided with an eyebolt, d, and having a slot, f,for the heelscrew. 2 5 E are brace-plates secured to the standard andfoot by bolts 9 g g.

H denotes a saddle provided with a slot, h, stirrups h It, and bolt K,screw-threaded to receive the nut 7c.

L denotes a clevis.

The beam A is mortised to the standard B. The brace-plates E are rigidlyfastened to the standard B by the bolts gg, the upper bolt, 9, passingthrough the mortise and the tenon on the beam. The foot D is secured tosaid plates by the bolt 9. This bolt is journaled in the plates to admitof the adjustment of the foot. The bolts 9 g g are preferably headed atone end, the opposite end being screw-threaded 0 to receive nuts. Thefoot D is provided with a bolt, (2, about five and one-half inches long,having an eye formed on its upper end, the lower end beingscrew-threaded to receive a nut adjusted under the foot, as shown inFig.

l. The slotf is about an inch and a half long, out lengthwise with thefoot, as shown in section in Fig. 1, and wide enough to admit aheel-screw.

The bracerod G is about fifteen and a half inches long, the upper partbeing screwthreaded for about eleven inches and provided with nuts 6 c.It passes obliquely through the beam, and is extended in a straight lineto meet the foot D at an angle of about sixty degrees,

as shown in Fig. 1. The lower end. of this red has a hook formed thereonto engage with the eyebolt d.

The saddle H and stirrups h h are formed in one piece, preferably ofmetal, having the slot h running lengthwise, as shown in Fig. 2, k abouttwo and a half inches long, through which the bolt K passes, the saddlebeing clamped in position upon the beam by the nut is.

In operation, when it is desired to change the inclination or pitch ofthe plow-point, the nuts 6 e are adjusted up or down upon the brace-rodto elevate or depress the foot D. It will be seen that the brace-rod andeyebolt take-the heavy strain off of the braceplates and support thefoot from above and beneath and throw the strain upon the beam. The slotfin the foot for the heel-screw allows of the adjustment of differentkinds of plow-points without any change in the shoulder that holds thepoint in position. The clevis-support, consisting of the slotted saddleand stirrups, is placed on the beam, as shown in Fig. 1, the clevis Lresting in the stirrups. To elevate or depress the clevis,the not It isloosened and the saddle slid forward or backward, as desired, and thenut tightened to clamp the saddle in position.

My plow stock or frame combines great strength with simplicity ofconstruction. The connection of the brace-rod to the foot through theeyebolt allows the rod to turn in the eye as the foot is adjusted,avoiding the necessity of mutilating the beam and other parts of thestock or frame to accommodate the change of 0 position of the brace-rodin adjusting the pitch of the plow, as was heretofore the case. Moreover, it will be seen that from the connection and position of thebrace-rod the tension upon it is lengthwise and not crosswise, throwing5 the strain directly upon the beam and avoiding the liability ofbendingor breaking the rod. The parts of the stock or frame are so adjustedthat they may be readily detached to economize space in shipping orrenewal in case of damage.

WhatI claim as my invention, and desire to secure by Letters Patent, is

1. The herein-described plow stock or frame, consisting of the beam A,having an oblique perforation formed therein, the standard B, thebrace-plates E E, secured to the beam, standard, and foot, theadjustable foot D, hinged to said braoeplates, the eyebolt d, secured tosaid foot, the brace-rod O, passing obliquely through the beam andhaving its lower end linked or hinged to eyebolt d, and means,substantially as described, for securing said rod in its adjustedposition, substantially as and for the purposes set forth.

2. In combination with a clevis, the adj ustable clevis-support adaptedto be fitted to a plow-beam and consisting of the slotted sad 2o dle H,having stirrups h h, and bolt K and adjusting-nut 7c.

8. A detachable clevis-support consisting of a slotted saddle, H,provided with stirrups h h, adapted to be adjusted forward or back- 25
